So the dropping of ctf sections makes sense.
Yes. > The missing COPTS was an accident or fallout from some other changes? Isn't it specified in -current? I think -O2 comes from MI src/sys/conf/Makefile.kern.inc: https://nxr.netbsd.org/xref/src/sys/conf/Makefile.kern.inc?r=1.268#69 On netbsd-9, GENERIC build uses -O2: --- % /s/netbsd-9/src/obj.zaurus/tooldir.NetBSD-9.0_RC1-i386/bin/nbmake-zaurus init_main.o # compile GENERIC/init_main.o /s/netbsd-9/src/obj.zaurus/tooldir.NetBSD-9.0_RC1-i386/bin/arm--netbsdelf-eabi-gcc -mfloat-abi=soft -ffreestanding -fno-zero-initialized-in-bss -fno-delete-null-pointer-checks -O2 -msoft-float -fno-strict-aliasing -fno-common -std=gnu99 -Werror -Wall -Wno-main -Wno-format-zero-length -Wpointer-arith -Wmissing-prototypes -Wstrict-prototypes -Wold-style-definition -Wswitch -Wshadow -Wcast-qual -Wwrite-strings -Wno-unreachable-code -Wno-pointer-sign -Wno-attributes -Wno-sign-compare -mcpu=xscale --sysroot=/s/netbsd-9/src/obj.zaurus/destdir.zaurus -Dzaurus -I. -I../../../../external/bsd/libnv/dist -I../../../../../common/lib/libx86emu -I../../../../../common/lib/libc/misc -I../../../../../common/include -I../../../../arch -I../../../.. -nostdinc -DCOMPAT_UTILS -DCOMPAT_44 -DDIAGNOSTIC -DW100_LCD_WRITETHROUGH -D_KERNEL -D_KERNEL_OPT -std=gnu99 -I../../../../lib/libkern/../../../common/lib/libc/quad -I../../../../lib/libkern/../../../common/lib/libc/string -I../../../../lib/libker! n/../../../common/lib/libc/arch/arm/string -c ../../../../kern/init_main.c -o init_main.o /s/netbsd-9/src/obj.zaurus/tooldir.NetBSD-9.0_RC1-i386/bin/nbctfconvert -g -L VERSION init_main.o --- zaurus/conf/INSTALL has COPTS="-Os" in its config, though. --- Izumi Tsutsui
